The "40-45% Webinar Show-Up Rate" Benchmark Everyone Cites Is Fake

The “40-45% webinar show-up rate from paid traffic” figure you may have read is not a benchmark. It is two fabrications, stacked. The first invents a joint study that none of the three companies named in it ever published. The second takes that invented number and relabels it as a paid-traffic figure the first page never claimed to be. This post traces both steps, checks the invented number against what the three named companies actually publish, and names the sourced range that should replace it.

Every time “40-45%,” “41.6%,” or “12,400 webinars” appears below, it appears next to the reason it should not be trusted — because the point of this page is to make sure that number never circulates again without its debunking attached.

What is the “40-45% from paid traffic” webinar benchmark, and where does it show up?

Search anything like “webinar show-up rate paid traffic” or “is 40% webinar attendance normal” and you will eventually land on a page whose opening line states, verbatim:

“Industry research shows median live attendance rates of 40–45% from paid traffic.”

That sentence is the only paid-traffic webinar show-up-rate benchmark that exists anywhere on the open web. Not one platform vendor — not ON24, not GoTo, not BrightTALK, not Goldcast, not Demio — publishes a figure segmented by traffic source. So when an operator running Meta or YouTube ads to a webinar asks what to expect, this is the specific-sounding answer that fills the gap. It does not survive a single click back to its source.

We check webinar benchmarks against their original source before repeating them — the same discipline behind the real number, by traffic source — and this one fails at the first click.

Where did the “12,400 webinars analyzed by ON24, GoTo, and BrightTALK” number come from?

Trace the “40-45%” claim back one link and it leads to a different site making a different, more specific-sounding claim. Its exact wording:

A real benchmark discloses a sample size, a collection period, and a link to the underlying report — the way ON24’s own 2019 report names 22,922 webinars and 1,600+ organizations. This claim discloses none of that for a study spanning three companies that are, individually, competing webinar platforms with no disclosed reason to pool data with one another.

That absence is itself a reason to expect a citation rather than take the sentence on faith. Nobody who actually ran a 12,400-webinar cross-vendor study would describe it in one unlinked clause and move on.

How did a fabricated median become a “paid traffic” benchmark?

The second page does not invent a new number. It relabels the first one.

Read the two pages side by side and the pattern is visible: an unsourced number acquires a second, more specific-sounding unsourced claim the moment someone else repeats it. That is how a made-up figure becomes “industry research” two clicks later — and it is why the safest rule for any statistic naming more than one company is to open the link, not to trust the sentence.

Does 41.6% match what ON24, GoTo, and BrightTALK actually publish?

No. Here is what each of the three named companies has actually published, on its own, next to the invented figure attributed to all three of them jointly.

None of those three real, individually published figures is 41.6%. Note also that these are enterprise figures — marketers emailing their own opted-in lists — and not a paid-traffic benchmark either. They are shown here only to demonstrate that the invented 41.6% does not match any real published number from any of the three companies it claims to summarize.

One more detail worth naming: ON24 itself has published two very different headline figures five years apart — 55.9% in 2019 and 60% in a 2026 blog post that discloses no webinar count. If a single vendor’s own headline number can move that much on its own data, a precise-to-one-decimal 41.6% attributed to three vendors at once, invented rather than measured, should have been the first thing anyone asked a citation for.

Why does a fabricated statistic like this spread unchallenged?

Three things make this fabrication durable rather than a one-off. It names prestigious, real companies, which borrows their credibility without needing their cooperation. It answers a question nothing else answers — no legitimate platform benchmark segments by traffic source, so an operator asking specifically about paid traffic finds a vacuum everywhere except here. And it is precise: “41.6%,” not “around 40%,” reads as measured rather than estimated, even though that precision is fabricated, not measured, and is exactly what should have triggered a citation request.

Both pages were still live and unchanged when this trace was last checked, on 27 July 2026. Neither carries a correction, and we found no statement from ON24, GoTo, or BrightTALK addressing the claim anywhere in their own published materials.

That combination — a specific number, a prestigious set of names, and no competing answer anywhere else — is exactly the shape of claim a search snippet or an AI assistant is built to surface first. It is confident, on-topic, and it sounds sourced. Whether the reader is a person or a language model, the check that would catch it is the same one: follow the link.

So what does the sourced evidence say about paid traffic?

Honestly: nobody has published a webinar show-up-rate benchmark segmented by traffic source, paid or otherwise. That absence is the reason the fabrication above exists in the first place — it is the only page pretending to answer a question the real data does not answer. What does exist is a set of published populations structurally closer to a cold or bought audience than the enterprise benchmarks most people have seen.

Those four sources converge on roughly 21–36% for populations that resemble a cold or syndicated audience — not the fabricated 40–45%, and not the 44–60% enterprise figures from ON24 and GoTo either, which measure marketers emailing their own opted-in lists. None of the 21–36% figures are segmented by traffic source specifically. They are the closest published analogues available, and they are labeled as analogues, not as a direct answer.

The full breakdown of every one of these datasets — what population each one actually measures, why the published figures disagree by up to 39 points, and every self-reported show-up rate we could find from operators running paid traffic themselves — is on the real number, by traffic source. That page is where the 21–36% range gets sourced properly; this one exists only to make sure the fabricated 40–45% number stops circulating unchallenged.

Frequently asked questions

If a client, a boss, or your own search handed you the fabricated “40-45%” figure as what to expect from paid traffic, the number to actually build a plan around is not on this page — it is on the real number, by traffic source, sourced against every population it compares yours to. Once you know your own baseline, how to increase webinar attendance ranks the tactics that might move it by the quality of the evidence behind each one, not by how confident the copy sounds.
